What is the meaning of biblical imagery?

Biblical imagery is when God takes truths and teaches those truths with images or stories and those examples of what has happened in the past help us to better understand those complicated truths. Jesus does that with parables in the New Testament. God also does that with the stories of the Old Testament. We understand the concept of walking by faith more when we see how Abraham had to leave everything familiar to him and travel for years without knowing exactly where he was going in the book of Genesis. We understand the leading of the Holy Spirit better when we see how the early Israelites had to follow a cloud by day and a pillar by night while they were wandering in the desert those forty years. We understand that the battle of sin is a war and we must not ignore the danger of sin when we read how the Israelites had to fight the Moabites, Canaanites and Hittites because they didn't see their threat at first, disobeyed God and then those people became a thorn in their side.
